With the widespread nature of wireless internet and internet of things, data have bloomed everywhere. Under the scenario of big data processing, privacy and security concerns become a very important consideration. This work focused on an approach to tackle the privacy and security issue of multimedia data/information in the internet of things domain. A solution based on Cryptographical Digital Signal Processor (CDSP), a Digital Signal Processor (DSP) based platform combined with dedicated instruction extension, has been proposed, to provide both programming flexibility and performance. We have evaluated CDSP, and the results show that the algorithms implemented on CDSP all have good performance. We have also taped out the platform designed for privacy and security concerns of multimedia transferring system based on CDSP. Using TSMC 55 nm technology, it could reach the speed of 360 MHz. Benefiting from its programmability, CDSP can be easily expanded to support more algorithms in this domain.
随着无线互联网和物联网的广泛普及，数据已经无处不在。在大数据处理的场景下，隐私和安全问题成为一个非常重要的考虑因素。本工作专注于解决物联网领域多媒体数据/信息的隐私和安全问题。提出了一种基于密码数字信号处理器（CDSP）的解决方案，这是一种基于数字信号处理器（DSP）的平台，结合了专用指令扩展，以提供编程灵活性和性能。我们已经对 CDSP 进行了评估，结果表明，在 CDSP 上实现的算法都具有良好的性能。我们还针对基于 CDSP 的多媒体传输系统的隐私和安全问题设计了平台，并进行了布线。该平台采用 TSMC 55nm 技术，速度可达 360MHz。得益于其可编程性，CDSP 可以很容易地扩展以支持该领域的更多算法。
